Now if you are going with a 205/60/15, what type of driving style do you have. Are you looking for an All-season tire that performs extremely well at cost of treadlife, or an all-season tire that wears well at the cost of performance.
Here are my suggestions:
I usually try and stick with a tire that has a good mileage warranty, if not then a good tread life, while not loosing their performance characteristics. To me, that shows the manufactuer tried making a superior tire all the way around.
My new favorite for the value, that took over the Firestone Firehawks SH30 are the Dunlop SP Sport A2. They have a 50,000 mile warranty just like the Firehawk SH30 did, a 420 AA A rating, instead of the Firehawk SH30's 460 A A. Now the "AA" rating is the highest you can get for wet traction, and the treadwear is ated in the 400s which means they will last. H-rated and performance minded, while the SH30s were more on the touring side. This is the bang for the buck. Since it is new, I would ask Luke more about what they think and if any testing has been done on these.

The Firestone Firehawk LH that you mentioned are standard touring tires. They are more focused on long wear and quiet ride. Since the Dunlops are in the High-Performance All-Season category, you know they can handle better in those situations, and since they re H-rated All-Season, you would be surprised to see how well they work on MBs and how quiet and smooth a ride they can be as well.
If you want a nicer Performing tire, then I would Suggest the Bridgestone Potenza RE950 or Dunlop SP Sport 5000. However, I believe the SP SPort A2 are one of the best new tires and very balanced in its characteristics. Its something I would put on my car for my father since he is just touring for the most part, but in emergency situations you know it can handle as well. And If I ever wanted to drive it, I know the handling factor is still there, without sacrificing All-season capabilities.
Take Care, Good Luck.
